I've also heard streptococcal and pneumococcal viruses. They don't know.

I’ve had Type 1 Diabetes since childhood and they’ve been saying the same thing about that for 35 years. Some link to EBV or other virus that triggers it with the right genetic and environmental conditions.

I heard of it not to long ago

Yes I did, 20 years ago. I think it is one of many things that trigger MS/ our immune systems.

I've read about the EBV link, but some others have suggested a more generic viral link/cause -- not just EBV but a number of viruses could cause that triggering effect.

FWIW, a 2022 MyMSTeam article on the EBV vaccine: (https://tinyurl.com/3ajck6bd).

But for me, I want that potential "MS vaccine" to stop progression ( https://www.youtube.com/watch?v=ML700hPtJmI) but that video is a couple of years old so I'm guessing that's not panning out. And I want "remyelinating drugs" (still said to be 5 years or so into the future). 🙂
